The Season Six premiere of Grey's Anatomy begins shooting on July 15.

According to inside sources, casting directors are currently looking for actors to play the guest roles in this episode (the medical drama's 102nd overall).

One role in particular listed in the Greys' Anatomy premiere casting call caught our eyes: Producers are looking for someone to play a Catholic priest in his 60s.

Could this possibly mean that Meredith (Ellen Pompeo) and Derek (Patrick Dempsey) are finally getting married? Like for real married, like in a church?

Or on the flip side, could someone be receiving their last rites, like perhaps Dr. George O'Malley, since actor T.R. Knight is not returning for Season Six?

What other characters can we expect in the sixth season premiere?

The producers are also looking for an 18-year-old male patient, Andy Smith, and his mother, Pam, for a two-episode arc, in addition to what appears to be a few foreign ladies backpacking across the United States who end up in the hospital. Sounds like it'll be good.

This episode of Grey's Anatomy will be written by executive producer Krista Vernoff, one of the show's top writers over the years, and directed by Ed Ornelas.
